Description
Technical field
The present invention relates to a kind of working method of yellow phosphorus, a kind of specifically phosphorus fine ore is made the preparation method that ball is produced yellow phosphorus.
Background technology
Yellow phosphorus is to make red phosphorus, phosphoric acid, Vanadium Pentoxide in FLAKES, phosphorus trichloride, thiophosphoric anhydride, other compounds of phosphorus thiochloride and phosphorus, can be used for siccative, agricultural chemicals, spices, dyestuff, organic synthesis industry such as phosphoric acid ester, at machinery, all there is application in a plurality of fields such as weaving and national defense industry, and the processing of present yellow phosphorus all is main raw material with the Rock Phosphate (72Min BPL), with coke, after the silica mixing fragmentation, produce yellow phosphorus through electric furnace again, because the not even harmful carbonate content of size is too high after the ore reduction, causing absorbing heat energy decomposes irregular, make it power consumption and material loss is excessive, chemical time is long in the heat-processed, production capacity is low, cost is excessive, particularly in broken and heat-processed, dust and carbon monoxide emission are serious, present yellow phosphorus processing enterprise has become the highly energy-consuming of China, maximum discharge, the enterprise that high pollution three is high is that current emphasis one of is reorganized the enterprise.
Summary of the invention
The objective of the invention is to solve the technical deficiency of above-mentioned existence, provide a kind of phosphorus fine ore to make the preparation method that ball is produced yellow phosphorus.Utilize the phosphorus fine ore that produces in the ore dressing process, be made into composite pellet of uniform size, be made as the yellow phosphorus finished product by electric furnace after drying by binding agent.Have the production capacity height, power consumption is low and reduces the characteristics that raw materials consumption, cost descend at double.
The present invention includes phosphorus fine ore, coke powder, ground silica and binding agent required raw material humic acids and sodium hydroxid, the technical scheme that is adopted is: feed composition is with every production 1000Kg yellow phosphorus finished product, and required weight is calculated as follows:
Phosphorus fine ore 7100～8500Kg
Coke powder 1800～2000Kg
Ground silica 1800～3300Kg
Humic acids 130Kg
Sodium hydroxid 65Kg
The concrete preparation method's branch of the present invention following steps are carried out:
Step 1: put into the ball mill profit by the required component of production 1000Kg yellow phosphorus finished product together by formulation weight and grind and mix;
Step 2: humic acids and the clear water five times of sodium hydroxid mixing back adding are stirred, that is: 1000Kg is warming up to 90～98 ℃, and it is stand-by to become binding agent;
Step 3: will moisten the mixed work in-process of mill and send into biaxial rneader and add binding agent and stir;
Step 4: above-mentioned work in-process are put into the stirring-cage type handling machinery be transported to the pressure ball nodulizer and be processed as composite pellet of uniform size;
Step 5: the composite pellet that processes sent into make ball disk, tumbling;
Step 6: polished composite pellet is sent into the carrier bar drying machine carry out drying treatment, dried water ratio≤0.5%, the bearing resistance 〉=200Kg after fixed;
Step 7: dried composite pellet is put into vibratory screening apparatus, and sieving goes out dust;
Step 8: step 6 work in-process in funneling crane is sent into the container of high temperature material making, are kept dry by hot blast through hotblast stove again;
Step 9:, send into and be made for the yellow phosphorus finished product in the yellow phosphorus electric furnace with the work in-process that keep dry.
Its phosphorus pentoxide content of phosphorus fine ore 〉=32% in the above-mentioned prescription, fixed carbon content 〉=80% of coke powder, the dioxide-containing silica of ground silica 〉=99%.
In the preparation method:
The described composite pellet that is processed as in the step 4, the diameter of its pelletizing is 20mm.
Drying treatment in the step 6, the temperature of its carrier bar drying machine are divided into four sections, and one section is 50 ℃, two sections 100 ℃, three sections 150 ℃, four sections 300 ℃.
Technique scheme that the present invention passes through, the phosphorus fine ore that has utilized ore dressing to produce, be shaped to composite pellet by binding agent through pressure ball, because big or small uniformity, the harmful carbonate foreign matter content of ground phosphate rock is low and do not have a dust, when in sending into electric furnace, heating, heat energy can be full and uniform be penetrated into internal layer, chemical reaction velocity is fast, it is steady to make it furnace gas pressure, phosphorus mud is few, furnace charge is difficult for the crust and the material that collapses, compare with conventional art, production capacity was calculated by ten thousand tons of stoves/year, per hour can produce the 3000Kg finished product, than conventional art per hour 1000Kg improve about 2 times of work efficiency, power consumption drops to 10000～13000Kw/h by original yellow phosphorus 16000～20000Kw/h per ton, and raw materials consumption is produced 1 ton by former 16～18 tons, drop to and produce 1 ton of finished product about 10 tons, production cost drops to about 8000 yuan/ton by former 14000 yuan/ton, and five phosphorus oxide content in the waste residue drop to about 0.5% by former 2.5%, and the carbon monoxide emission that produces in the production process is by original 2500～3000m
3/ ton drops to 1500～2000m
3/ ton, simultaneously, pass through the technical program, the electrode of electric furnace uses not fragile, the fusion time was short after furnace charge was gone into stove, have that output height, cost are low, power consumption less and reduce the unusual effect of disposal of pollutants, meet very much the industry policy that the existing yellow phosphorus processing enterprise of China rectifies, be the modern technique that this year, phosphorus production must be used.
